To all whom-it mayconoera:

Be it known that-I, METHOD F. Srr'rA, a

Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Windows, of which the following is a specification.

" in provision is made for ventilation by tilt--- ing the lower sash inward and at the same This invention relates to windows of that class which are provided with sashes that may be raised and lowered.

The invention has for 1 construction wherein: the sashes, when closed, will be disposed one above the other in substantially the same plane, and wheretime automaticallylowering the upper sash in a substantially automatic manner.

. A further object of the inventionis to produce a window of this class in which the sashes may be conveniently reversed or turned over to provide forcleaning the outer faces of the glasses from the inside of the room. A further object of the lnvention is to produce a window of .the class described wherein provision shall be made for tight-1 ening the sashes against rattling and theinsideof a room. Fig. 2 is a vertical sectional view taken on the line 22 in Fig.

1, and showing the sashes closed. 3,

. showing the bottom sash reversed for clean-' against leakage of air when desired.

With these and other ends in view which will readily appearas the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying'drawings has been illustrated a simple and preferred formof the inventiop,=it--being, however, understood that no lin'i'i ation is necessarily madeto the I precise structural details therein exhibited,

but that changes, alterations and mod1fica-- tions within the scope of the claims may be resorted to when desired.

2. Fig. v8 is a side view, showing the two WlIidOW. sashes detached 'from;the frameor casing, and showing alsov the sash cord whereby they are connected and the pulley over which said cord is guided. Fig.9 is a perspective detail, view of one of theslides cooperating with the window casing.

, Corresponding parts in the several figures are denoted by like charactersof ref-- i a V Thesides. 15 of the window frame are.

provided with outer beads 16which extend all the way from the sill 17 to the cap 18...

Parting beads 19 are also used, but said parting'beadsonly extend from the cap about half way down toward the sill in order that thebottom sash2Q may be tilted r inward beneath said parting .beads,as will I:

be hereaft 'd cribed. .Theinn b h I moldings 22 also extend from the1cap,b 1t terminate about midway between th ap andqsill- The top sash 23 is-normally-Ipo sitioned between the outer beads 1 and: the

parting beads in the upper portion of the window frame, and the bottom sash when; closed is posltioned directly beneath the top sash, abutting on the outer beads, the meetrespectively, being jointed together to form a weather-proof joint.

v The sashes are "connected together at each side by a sash cord 26, the two f ends of about midway between the. top andkbottom ing rails 24, 2,5 of the bottom and top sashes, 1

'whi ch are connected respectively withth'e",

side rails of -thelower and upper sashes 5.

of each sash, the connections being effected" in such a way as to permitthe sashesto swing'p'ivotally thereon The'side rails of r the sashes are each provided with a groove '27 that extends upwardly from the point 28 at which the sash cord is connected with thefside rail in order to accommodate said sash cord. Each sash cordi's trained v over I a guide pulley 29 near the top of the wini i I dow frame, said pulley being located midway between the outer and inner beads, a

cut away for the accommodation thereof,

portion of the parting bead having been said pulley being also of such a diameter that the ends of the cord guided thereover will normally lie about midway between the parting bead and the outer and inner beads, respectively. The sash cord 26 is also adapted to be guided beneath a pulley 30 located directly below and closely adjacentto the lower end of the parting bead 19.

Each side of the window casing is equipped with a slide 31, said movable bead member being positioned beneath the parting bead 19 and molding 22. Each bead member 31 is provided with headed studs 32, 33 that are guided in slots in the sides of the casing, said slots being protected by correspondingly slotted facing plates 34:, 35. The slots3G, 37 are inclined downwardly and outwardly, and the slot 36 in the upper facing plate has an inward extension 38 from the upper end thereof which terminates flush with the inner face of the window casing where it is protected by a pivoted guard plate 39. It will be seen that when the headed studs 32 of the bead member 31 are guided in the slots 36, 37, pressure in a downward direction on the slide will force it downwardly and outwardly against the lower sash, assuming the latter to be 'in position, thus forcing the said lower sash outward against the outer bead 1G and holding it tightly so as to prevent rattling and leakage. At the same time, the lower end of the upper sash will be forced in an outward direction, owing to the existence of the joint between the meeting rails, and the upper sash will thus to alarge degree be held tightly and securely against rattling and leakage.

When the window is closed.the upper sash will be positioned directly above the lower -limit of the slots 36, 37. after which said head members may be tilted in an inward direction until the upper guide studs are arrested by the guard plate 39. The bottom sash 20 may now be swung inward, as seen in Fig. 3. The sash cord at each side will thus l'lQCOlllt slackcncd to some extent, that portion thereof which previously was positioned between the guide member 30 and the upper end of the bottom sash being straightened out in alinemcnt with the remaining portions of the sash cord. and the top sash will thus be permitted to drop gravitationally to some extent permitting air to enter in an upward direction between the lower portion of the top sash and the upper portion of the bottom sash and also above the top sash. Increased ventilation will be provided by partly-raising the bottom sash between the parting bead 19 and the molding 22, thus pern'iitting the top sash to becorrespondingly lowered. By swinging the guard plates 39 on their pivots the upper ends of the bead members 31 may be swung inward and downward, thus permitting the bottom sash to be swung pivotally about the ends of the sash cord and presenting the outer side inward for cleaning purposes, as seen in Fig. at. By raising the bottom sash to its'full extent, the top sash will be correspondingly lowered, and said top sash may now be swung pivotally, as seen in Fig. 5, for the purpose of cleaning the outer face thereof.

As will be seen from the foregoing description, taken in connection with the drawings hereto annexed, I have provided a window of very simple and inexpensive. construction wherein sash weights, springs and other cumbersome and expensive-accessories are dispensed with, as well as the expensive construction of the window frame which is necessary in order to provide pockets for the sash weights when the latter are used.

A very valuable feature ofthe invention resides in the facility with which either the bottom or the. top sash may be inverted for the purpose of cleaning the outer face thereof.

The general construction is simple and inexpensive, as well as thoroughly efficient for the purposes for which it is provided.

Having thus described-the invention, what is claimed as new, is

1. In a window, a casing,pulleys arranged vat the upper portion of said casing and guide pulleys arranged below the first named pulleys, in combination with a top and a bottom sash and cords connecting said sashes and secured to the sashes at intermediate points of their heights, said cords passing over the pulleys at the upper portion of the casing and beneath the guide pulleys, whereby pressure in an outward direction on the bottom sash when at its lowest position will tension the cords to exert a lifting action on the top sash.

2. In a window, a casing, a pulley arranged at the upper portion of said casing, and a guide pulley arranged below the first named pulley. in combination with a top and a bottom sash. and a cord connecting said sashes and secured to the sashes at intermediate points of thei rheights, said cord passing over the pulley at the upper portion of the casing and beneath the guide pulley, and an inside bead slidably and pivotally mountcd so that the upper end of the bead may be moved inward to engage a stop,said head heing movable downwardly and outwardly in In testimony 'whereof I affix my signature the direction of the bottom sash to force thein presence of two witnesses.
